The method len() returns the number of elements in the list or length of the string depending upon the argument you are passing.
How to implement without using len():
1. Take input and pass the string/list into a function which return its length. 2. Initialize a count variable to 0, this count variable count character in the string. 3. Run a loop till length if the string and increment count by 1. 4. When loop is completed return count.
